Jul.11 (GMM) McLaren driver Heikki Kovalainen on Friday said the British team may not race at next Sunday's German grand prix the 'shark fin' engine cover it debuted at this week's Hockenheim test.

His teammate, joint championship leader Lewis Hamilton, told reporters earlier this week that he didn't notice a difference when he turned laps with the new bodywork.

"We will test it again I think," said the Briton.

Finn Kovalainen, however, said in a team interview that he thinks the piece was an "advantage" over the standard configuration.

"But it's still too early to say; maybe Hockenheim is not the best place to try this new wing and we need to see if it is affected by crosswinds -- it was quite windy at the Hockenheim test, but we didn't seem to be too affected by the wind," the 26-year-old added.

"It's definitely encouraging for the future."
